Question about 1994 Volvo 850
The hydraulic tappets do not control the valves; just the valve lash. It will have NO effect on the opening and closing of the valves. Just makes noise (cluck cluck) till they fill up.
Sounds like you have bad fuel. Drain the tank by jumping the FP relay and by attaching a hose to the line that connects to the fuel rail. Do it in 1 minute intervals to avoid overheating the FP.
Do not run the starter that long unless you want to install a new one!!

Does it seem to turn over really quickly? It could have to do with the valves because they are controlled by hydraulics, so when they lose pressure they do not activate. It may take up to 20 minutes to bring the pressure up. Just keep turning it over and I'll bet it will eventually go. You will likely drain at least 1 battery, so have some jumper cables handy. Also, don't over work your starter or you may burn it out, give it some breaks.
